Description: An assessment was made of a twelve-month old nursery progeny test of Hevea hybrids in order to select and recombine the high latex-yielding Hevea trees which had a rapid growth rate. The plant materials grown for the study included open-pollinated progenies, progenies of F1 backcrossed to primary clones of H. brasiliensis, progenies of F1 hybrids crossed with F1 hybrids and progenies of open-pollinated H. brasiliensis used as control. A number of characteristics such as yield of dry rubber per tapping by Mendes early test, plant height and stem diammeterwere assessed. The preliminary results showed that the progeny of selected F1 wind-pollinated hybrids (illegimate) was significantly faster in growth compared with progeny of primary clones of H. brasiliensis similarly open-pollinated.
